WlPlNG ATTACHMENT F'oR POWER EMBOSSING-PRESSES.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed April 15, 1905. Serial No. 255,782-

. Power Embossing-Presses, of which the following is a specification .containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in wiping attachments for power embossingpresses.

The object of my invention is to equip an embossingpress with an endless wiping mechanism, which is to be substituted for the wiping attachment now used on the presses upon the market.

A further object of my invention is to convey the endless wiper through a solution in order that the ink'may be removed during its motion and cleaned and dried.

In the drawings, Figure 1 is a side elevation of my device shown in operative position upon theembossing-press. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectional view. Fig. 4 is a diagram of the Wi er and pressure head.

efore describing my invention in detail I desire to state that the upright 1, bracket 2, table 3, ink-roller 4, ink-distributing mechanism 5 and its brackets 6 are old and form a part of the embossing-presses now upon the market. The dotted lines 7 and 8 indicate the rollers now used, on which a strip or tape of paper is carried and conveyed underneath the adjustable wi er-head 9 for wiping the ink from the dies before the impression is made. The adjustable wiper-head 9 referred to is mounted between the brackets 2 of the frame and are held in adjustable position by means of the spring-actuated bolts located on each side, as shown in Fig. 1.

I will now describe my improvement, which consists of extending the arms 10, car rying on their ends a roller 11, which is supported in adjustable bearings 12. On the arms 10 is also revolubly mounted a roller'13, and suspended below the arm is an idler 14. A pan or basin 15 is also supported by the arms 10, in which is contained a liquid solution or a powder, as desired, which is for the purpose of removing inks from the endless wiper 16. A roller 17 is supported by the less wiper 16.

arms 10 and located in the basin 15. A pair ofiwringer-rollers 18 are also supported by the arms 10, between which is passed the end- The endless wiper 16 is composed of a material suitable to absorb the inks from the surface of the plate and sufficiently durable to stand the strain caused by the pressure of the moving wiping-head 9. The endless wiper is revolved or placed in operation by the gears 19, connected to any desirable operating mechanism upon the machine.

The operation of the endless wiper is a step-by-step movement, only advancing at a period when the pressure head is being raised, and during its motion the endless wiper. is conveyed under the roller 17 through the cleansing liquid, and the moisture is squeezed from the same by means of the rollers 18. In this manner the wiping device can be continuously used without the necessary removing of the tape after each job, as is now being done with the present and old style of wiping devices.

I show the old mechanism in dotted lines to clearly illustrate the difierence between the old device and my improvement The idler 14 will at all times retain the endless wiper in a taut position and by means of its springs will give the wiper elasticity.

It has been found necessary in a device of this construction to locate the endless wiper under the adjustable wiper-head to come in contact with the printing-plate at a period when said plate is stationary, and at the mo ment the printing-plate is brought forward to be placed under the press the wiper-head is automatically raised. This operation will necessarily require the endless wiper to give sufliciently for this vertical adjustment, which is permitted by the use of an idler, as indicated by the numeral 14.

Having thus described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent, is

A wiping attachment for power embossing-presses comprising a pair of projecting arms in combination with the frame of an embossirw press, brackets formed on the lower sur ace of the projecting arms and roj ecting downwardly, a table projecting om the frame of the machine and to which is attached the lower end of the brackets, a wiper-head adjustably mounted within the brackets, a plurality of rollers carried by the projecting arms, a basin containing cleansrollers for removing the material from the 10 mg material secured to the under surface of endless wiper, substantially as specified.

the projecting arms and located between two In testimony whereof I have signed my of said rollers, three of said rollers located name to this specification in presence of two above the basin, and an endless wiper passed subscribing witnesses. around the rollers and under the wiper-head LOUIS M.
